(Forward), GeoLogic Associates (GLA) is submitting this <br /> summary report for the Forward Landfill groundwater treatment facility (GTF) to fulfill <br /> the requirements established by Waste Discharge Requirements (WDRs) Order No. 85- <br /> 2003-0080. <br /> The Forward.Landfill is an active facility located at 9999 South Austin Road in Manteca, <br /> California. Following detection of volatile organic compounds (VOCs) in groundwater, a <br /> Corrective Action Program (CAP) was implemented at the site in 1994 which includes <br /> four groundwater extraction wells (EW-1, E -2, EW-3, and EW-4) that pump <br /> groundwater through an air stripper treatment system to remove VOCs. The treated <br /> groundwater is discharged to an infiltration pond north of the Austin Road Unit of the <br /> Forward Landfill. In April 2009 extraction wells EW-3 and EW-4 were constructed as <br /> part of the enhanced CAP proposed for the Forward Landfill. Included herein is a <br /> summary of the water quality monitoring results for the GTF at the Forward Landfill for <br /> the second quarter 2009. <br /> CAP MONITORING PROGRAM RESULTS <br /> Under WDR Order No. R5-2003-0080, effluent monitoring consists of monthly analysis <br /> for pH and volatile organic compounds (VOCs), and effluent monitoring consists of a <br /> continuous record of flow; monthly analysis of pH, specific conductance (EC), and <br /> VOCs; quarterly analysis for total dissolved solids (TDS); and annual analysis of 24 <br /> metals. In addition, influent is monitored semiannually for pH, EC, turbidity, and VOCs. <br /> Del-Tech Geotechnical Support Services (Del-Tech)performs the operation and <br /> maintenance (O&M) duties and performs bimonthly inspections for the Forward Landfill <br /> GTF. The results of the bimonthly inspections are presented below and summarized in <br /> Table 1 and the field monitoring logs and laboratory results are attached. <br /> 16886 W.
